We usually use knives, graters, scissors, pencil sharpeners, a saw, and so on in our daily life for cutting. Do you know how these products are manufactured? They also are made of cutting tools. These cutting tools share a common property which is that they all change the shapes of things by cutting and producing chips. As we know, cutting tools are tools that cutting things to acquire the desired shape, cutting tools in our daily life cut fruits, vegetables, and wood. But the cutting tools produced by Zhuzhou Xinhua cemented carbide industrial co.Ltd cut harder materials such as steel, stainless steel, cast iron. MANUFACTURING PROCESS OF CARBIDE TOOLS Let’s see the manufacturing process of carbide. First, mix tungsten carbide with cobalt to make powder which can be classified as raw materials. The granulated mixture is poured into a die cavity and pressed. It gives a moderate strength like that of chalk. Next, the pressed compacts are placed in a sintering furnace and heated at a temperature of about 1400°Resulting in cemented carbide. After sintering, the content volume shrinks considerably. Also, the hardness of cemented carbide is at a level between diamond and sapphire and its weight is about twice as iron. Then, how do we cut this hard cemented carbide? What is Cutting? The figure on the right shows the

When we choose the turning insert, we should consider many parameters such as the insert geometry, insert grade, insert shape, and insert size, nose radius and entering angle to achieve good chip control and machining performance. First, we need know the inserts will be used for roughing, finishing or just doing some general turning. For roughing and general turning applications, Negative inserts are the strongest and the best option as it will allow deeper depths of cut and higher feed rates due to strong insert shapes and thickness. Negative turning insert Double and/or single sided High edge strength Zero clearance First choice for external turning Heavy cutting conditions If you are finishing, positive inserts are always the best option as these create less cutting forces and can therefore get away with lower depths of cut, eliminating vibration. Positive turning insert Single sided Low cutting forces Side clearance First choice for internal turning and for external turning of slender components   CNMG, DNMGand WNMG are the most popular roughing inserts. For heavier roughing operations, SNMGs are an excellent choice with a 45-degree approach angle allowing for larger depths of cut and reduced cutting loads. CCMT,DCMT, VCMT or VBMT are the most popular finishing inserts. For roughing applications, you would usually opt for a 0.8mm or 1.2mm radius depending on your machine’s horsepower and the depth of cut you

SIMM exhibition center     This year is special year which encountered COVID-19, and even other overseas countries are still fighting with VIRUS, Thank you for governments and all sacrifice volunteers for affords, it was successful at SIMM exhibition center without influence, exhibitors were blooming to visit and insult various of cemented carbide inserts , cutting tools , we XINHUA displayed many traits product, this shows turning insert, mill inserts, aluminum insert, cermet inserts, groove inserts etc, also offer goods scenarios for all of industrial user or agents, Thank you for supports, we will do our best as always.
